c# - Writing a topic pub/sub system -

-

I am writing client / server applications that will publish and subscribe to topics. I have some questions about architecture and the implementation of this project.

To install the base, I will first use C # (.NET 3.5) and I want to explicitly use raw socket / AIO / threads (not the first WCF, because I have a server And my customers want to tune up properly. Customers subscribe to most topics but can sometimes send commands to the server and publish data. Some clients may only be publishers.

  1. Do you think my server should have basic building blocks (per client, thread, iocp, ....)

  2. Does the client use the same network stream to listen to subscribing topics and to publish on command / server? How to wait for data and to write data at the same time, should it be done in a single thread?

(The sample code will be appreciated :))

  • The customer should use two streams - one for the list and the other to make things easier on both the client and the server side, again several threads Use async sockets to avoid managing.

    • Be sure to carefully manage locking with shared resources used by your asynchronous callback. If possible, the shared resources could not be as viable as possible. Managin's access to contemporary things is usually the worst part of any app.

    After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

    I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

    sql server - How can I determine which of my SQL 2005 statistics are unused? -

    -
    After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
